A large language model (LLM) is a neural network trained on a vast amount of text for natural language processing tasks, especially language generation.
LLMs can generate, summarize, translate and parse text in many contexts, and are a foundational technology behind modern chatbots.1
LLMs fall under self-supervised learning, which is Supervised Learning branch of Machine Learning, however, LLMs generates supervisory signals itself - not externally provided labels or "hints".
Currently in tech industry LLMs are incompetently mislabeled as AI.
